How about because Arnold doesn't stand a snowball's chance of winning unless he is closely affiliated with the Dems.?
By the way... I watched the LT Gov out there give a press conference yesterday, and is that guy ever talking out both sides of his mouth!!! He was talking all about how dangerous the recall is... about how Davis should stay in office... how Davis deserves more time... etc.
Then, he starts saying "here's how I'll do things once I'm elected", and more importantly, he said that he disagrees with those who feel that the recall is a vast right-wing conspiracy. He says that the people are tired of the poor job that Sacaramento has been doing, that this is the reason the recall is underway, and that he's the man to fix the problems.
I've never seen a politician who was able to go so far in different directions in one press conference.
